Hi everyone, Happy Monday!
I'm working for a company, and at the moment, we cannot image laptops using PXE.
We cannot ping Windows laptops on the same VLAN, but we can ping MacBooks.
The Network Team sets no firewall rules ping is not disabled, and it doesn't seem to be blocked by the Windows Firewall, checked advanced settings for inbound ICMP
It's also not blocked by the antivirus; we tested it with the antivirus turned off.
Any ideas on what could be the issue or where to check and troubleshoot?
Thanks in advance for any hints.
Regards
Decio

    Navigate to Control Panel > System and Security > Windows Defender Firewall. Click on "Advanced settings" and then "Inbound Rules." Find the rules for "File and Printer Sharing (Echo Request - ICMPv4-In)" and "File and Printer Sharing (Echo Request - ICMPv6-In)" and ensure they are enabled. If you're on a corporate network, Group Policy might block ICMP. Contact your IT administrator.

    Hi Decio pereira Use Ping with parameter -a, if this operation is successful, the destination IP exits and ping displays the corresponding host name. Then, Ping the computer local IP 127.0.0.1, if the node can't ping its local IP, the local stack isn't working.
